So Ji Sub and Yoo Seung Ho warmed the air at the shoot for So Ji Sub′s music video.

Yoo Seung Ho recently filmed the music video for the tracks from So Ji Sub′s mini album 6 O′clock...Sports Field. So Ji Sub will be appearing as the male lead, while the ′Little So Ji Sub′ Yoo Seung Ho will be appearing as a younger lead.

The two met on January 10 at a studio in Gwangju. Yoo Seung Ho had been shooting for six hours straight, in a scene where he meets with Park Shin Hye at a club and starts talking with her.

So Ji Sub and Yoo Seung Ho actually were unable to meet during their shoots, as they never appear together. So Ji Sub, however, took time off of his schedule to go see Yoo Seung Ho after wrapping up the shoots for his own scenes, even getting him snacks to thank him for his hard work.

So Ji Sub presented Yoo Seung Ho with a chocolate shaped like a heart, and Yoo Seung Ho joked, "Is this a confession of love, this red heart?"

The two stayed together between shoots, talking about the music video and So Ji Sub′s upcoming album.

Yoo Seung Ho praised So Ji Sub′s song, which he had heard while filming.

This is the third time the two have worked together, with the first being So Ji Sub′s music video for his digital single Lonely Life in 2008 and the second being a kimchi refrigerator commercial.

In the music video for 6 O′clock...Sports Field, Yoo Seung Ho will meet Park Shin Hye and fall in love with her, while So Ji Sub will lose her.

The four songs of the album will be combined together to make a 12-minute-long music drama, and there will also be music videos for each individual track, as the long music video will be re-edited to fit each song.

Director Hong Won Ki, who helmed the music videos for Seo Taiji′s Moai, Epik High′s Run and One, Girls′ Generation′s The Boys, B2ST′s Shock and Secret′s Madonna will be in charge.
